A facile effective stirring aging at room temperature prior to conventional hydrothermal treatment was employed in the template-free synthesis of micro- and nano-crystalline sodalites with two different initial gel compositions. The effect of initial Si/Al molar ratio, NaOH concentration and stirring aging time were investigated on the morphology and particle size of the...
مقدمه: پروتئین های وابسته به خانواده سیستم ترشحی دوجزئی می توانند درچسبندگی باکتری نقش داشته باشند. چسبندگی برروی سطوح، به عنوان یک عامل بیماریزایی، اولین گام در انجام فرایند تجمع باکتریایی می باشد. اسینتوباکتربومانی دارای توانایی ویژه ای برای کلونیزاسیون برروی سطوح مختلف است. هدف از انجام این تحقیق، شناسایی، مطالعه و بررسی نقش پروتئین های این خانواده در چسبندگی اسینتوباکتربومانی به سلول اپی تل...
Anode-supported micro-tubular solid oxide fuel cell (SOFC) offers many advantages over the electrolyte and cathode-supported confgurations in terms of simplicity, reliability, and efciency. In such design, the anode substrates should possess a highly porous structure, provide active sites reaction as well as serving good mechanical strength. This structure is desired to ...
onychomycosis due to the yeast and yeast-like fungi was investigated among the 147 patient who refered to the mycology laboratory of school of public health during the period of 11 months. the isolated yeasts and yeast-like fungi were examined by api auxanogram methed. the distribution of isolated microorganisms were c. tropicalis 10(7.4%), c.guillioimondii & (5.9%) cases and one case of each o...
در این تحقیق مطالعاتی برای بررسی و مطالعه اثر اسید آمینه های جایگاه اتصال کلسیم روی پایداری حرارتی آنزیم bmw آمیلاز-پلولاناز انجام شد. سه جهش براساس مقایسه توالی با آمیلاز های مقاوم به حرارت طراحی شد. بر اساس نتایج، جهش h58i افزایش 5/7 برابری در کارایی کاتالیتیک را نشان داد، ضمن اینکه در مورد جهش یافته s76p میزان وابستگی به کلسیم افزایش یافت و در غلظت های بالاتر کلسیم میزان پایداری این آنزیم اف...
